Tn sockets of the iin'esrnt type it. has been the. enstomanv practice torel rupon the insulating character of the camlehdnnm tube whirhsari-(mods the socket shell to alford the necessary insulation whichprotects the installation from accidental contact with conducting parts.Inasmuch as these candelabrmn sockets are ordinaritr of porcelain orglass they afford ellicient protection to this end. The eonnnoneandelabrmn inbes are thus rather fragile and it has been proposed tosubstitute therefor metallic or enameled metal tubes for the samepurpose. Inasmuch as this introduces a possible element of danger intothe installatiol'i by reason ol" the conducting. nature of the. metal itnecessary to provide an insulator between the shell of the socket andthe ('alnlelaln'um 1 ulnto prevent contact between the same.

in the embodiment oi my invention illustrated. l have shown a socketlody 10 comprising the usual insulating button rarr f ing on its l werfare an internally threaded invention 'thimble 11 which screws upon theupper end of the wire ronduit 12 through the holes 3} in which the wiresIt and 15 are. led to the binding serew terminals 16 and t? on the uppersurface of the socket body.
